LIPO BATTERIES

Number of Cells

Batteries can be connected in series (S) or in parallel (P). A LiPo

battery is advertised by voltage and capacity where each cell carries

3.7 volts. A 4S LiPo battery would be 4x 3.7V or 14.8V. The capacity

is listed in milli-amp hours or mAh, so a 5300mAh battery can

discharge a maximum of 5300 milliamp-hours or 5.3 amp-hours.

Please also be aware of the battery’s discharge current delivery

capability, or C-rating. A 25C, 5300mAh battery will deliver 132.5A of

current regardless of voltage.

Please note that the kV of a motor does not change with voltage, but if a

higher voltage is applied to the motor, it will try to spin the same propeller

at a higher rpm. This will cause the motor to draw more current and pos-

sibly exceed the maximum rated current of the motor. So, if a battery with

lower voltage is replaced with one with a higher voltage, it is recom-

mended that a smaller propeller be used to keep the current in check. If a

higher voltage battery is replaced by a lower voltage battery, the size of the

propeller can be increased to keep the motor at its rated current.

Another possibility to fine tune the power system’s performance is to use

another motor with higher kV to increase the current or a lower kV to lower

the current.

ELECTRONIC SPEED CONTROL (ESC)

An ESC is basically the device that controls your motor through your radio

system. Never run any RimFire motors with a brushed ESC. It will not

work and you may damage both the motor and the ESC. Always use a

brushless ESC. ElectriFly offers the Silver Series SS-60 and SS-80

Brushless ESCs (GPMM1850 and GPMM1860) that work well with the

RimFire 50mm motors.

The SS-60 ESC comes with 4mm female bullet connectors that plug directly

into the 4mm male connectors installed on the RimFire 50mm motors, so

no soldering is required. The SS-80 comes with 6mm female bullet

connectors and requires an adapter (GPMM3119). Also, these ESCs come

with a Deans

Ultra Plug

battery connector that matches the connectors

that are found on most batteries that it will use.

The ElectriFly Brushless Large Motor Mount combines ease of installation

with the adjustability to fit most motor applications. The Large Motor

Mount is designed to fit the bolt pattern of the Great Planes

.40-.70 and

.60-1.20 Nylon Engine Mount. This easily allows the conversion of a glow

powered plane to electric powered.

PROPELLERS

There is a wide selection of propellers available for electric use. The RimFire

50mm motors use high performance electric props such as the APC

E-series props. The larger the propeller used, the more current your motor

will draw. The smaller the propeller, the less current the motor will draw.

Shown are a few of the recommended electric props. Due to the large

range of propellers and the constant addition of new sizes, visit our web

sites at www.electrifly.com and www.greatplanes.com for the most

up-to-date listing of electric type props.

PROPELLER ADAPTERS

The RimFire 50mm motor comes with a prop adapter that mounts directly

to the motor case. If the RimFire 50mm motor needs to be mounted so

that the prop is mounted on the motor shaft, the motor requires an 8mm

prop adapter collet type (GPMQ4971) or set screw type (GPMQ4945).

Congratulations, you have just purchased one of the RimFire 50mm

power system components. All the components are sold separately to

allow you to customize your power system to your airplane. The

components needed to assemble your complete RimFire 50mm

power system are: RimFire 50mm motor, propeller, propeller adapter

and brushless speed control. This instruction sheet explains how to

determine what you will need and how to assemble each component.

Understanding Motors

kV (rpm/volt): This is a number that gets thrown around quite a bit

when talking electrics and it is important to know what it is. kV is the

number of rpm a motor will spin per each volt applied (rpm/volt)

under no load.

This means that a motor with a kV of 1000 when connected to a 12V

battery will try to spin at 12,000rpm (1000x12) under no load.

Likewise a 3500kV motor will try to spin at 42,000rpm (3500x12)

under no load.

When a propeller is attached to the motor, the motor will try to spin

the prop at the rated kV. Depending on the diameter and pitch of the

propeller (the larger the diameter or higher the pitch, the harder it is

to spin), the motor’s current draw can be increased or decreased.

There are meters available from your hobby dealer that measure

current and voltage.

Because every motor has a maximum current it can take based on its

design and cooling ability, the maximum size of propeller that can be

used with each motor can be determined. If the propeller is too large,

the motor will spin at a much lower rpm than its rated kV, causing it

to draw a lot of current and overheat. If the propeller/fan is too small,

it will require little effort (current) to turn the prop at the rated kV.

Ideally the motor should be matched with a propeller that causes the

motor to draw 80-100% of its rated maximum constant current. Once

a power system is set up, it can be fine-tuned by adjusting the propeller

size and measuring the amount of current the motor is drawing.
